▎ 摘　　要

NOVELTY - Electrode mixture comprises a lithium-containing transition metal oxide, an auxiliary conductive agent, a binder and an organic solvent. The auxiliary conductive agent contains at least one type of nanocarbon material chosen from multiwalled carbon nanotubes, carbon nanohorns, carbon nanofibers, fullerenes and graphenes. The binder contains a fluorine-containing copolymer that contains vinylidene fluoride units and fluorinated monomer units (excluding vinylidene fluoride units). The content of vinylidene fluoride units in the fluorine-containing copolymer is more than 50 mol% and not greater than 99 mol% relative to the total amount of monomer units. USE - The electrode mixture is useful in an electrode mixture layer of an electrode used in a secondary battery (claimed). ADVANTAGE - The electrode mixture is capable of forming an electrode mixture layer having excellent flexibility and adhesion to a current collector and capable of forming a secondary battery having excellent battery characteristics. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an electrode comprising a current collector and an electrode mixture layer provided on one or both sides of the current collector and formed by the electrode mixture.
